Stadler Finalizes SBB Trains

The cooperative project between Stadler and Swiss Federal Railways involved the production and deployment of sixty double-deck InterRegio trains to expand regional rail transport capacity across the Zurich region, the Swiss Midlands, and Western Switzerland. The cooperation required managing complex engineering and manufacturing coordination to ensure fleet reliability and on-time delivery. The trains have been in passenger service since mid-2023, accumulating over 23 million kilometres of operational mileage.

Technical Solution and Environmental Architecture
The RABe 512 trainsets incorporate advanced technical solutions, including a propane-based air conditioning system designed to offer higher environmental efficiency compared to conventional refrigerants. The vehicle architecture features high-capacity double-deck configurations optimized for passenger comfort and structural integrity. The production phase faced multiple operational hurdles, including global supply chain disruptions, the effects of the COVID-19 pandemic, and the structural impact caused by the flooding of Constellium's aluminium manufacturing plant in Valais, Switzerland, during the summer of 2024. Despite these external constraints, collaborative project management maintained production schedules.

Operational Performance and Maintenance Impact
The fleet's operational performance is characterized by high availability and consistent reliability across extensive service routes. The technical configuration of the sixty trainsets supports heavy commuter demand and maintains stringent safety standards. According to Lucius Gerig, Head of Division Switzerland at Stadler, delivering the vehicles on time and in outstanding quality demonstrates the results of close cooperation focused on successful service integration.
